The course gives to doctoral students from different disciplines the opportunity of both highly theoretical studies and numerical simulations of interactions of electromagnetic waves in the visible part of the spectrum (and adjacent UV and IR bands) with biological tissues. And to learn about modern optoelectronic sensor concepts and their applications in the

field of medical therapy and diagnostics. Interdisciplinary topics will be discussed and focused on the benefits and current applications of optoelectronics in medicine. Important definitions (such as radiation intensity, etc.) will be formulated and important methods will be described, in particular: radiometry, photometry, eye as a radiation detection field. UV, VIS, NIR spectroscopy, interferometry, scattering measurements, integration of spherical theory, etc.

Emphasis will be placed on modern theoretical approaches (i.e. mathematical and physical models), e.g. calculation of the light intensity distribution in biological tissue, theory of radiation transmission (e.g. theory and model Kubelka-Munk), etc. Students will be acquainted with the possibilities of numerical simulations of the given problems by aid of

modern SW products (like e.g. COMSOL Multiphysics, SEMCAD / Sim4Life, CST, etc.) which are working based on numerical methods FDTD, FEM, MoM, Monte-Carlo etc. Operating principle of the optoelectronic reflective and transmissive sensors. Measurement concepts for noninvasive detection of peripheral blood volume dynamics, clinical examples and typical examination tests. Principles and applications of functional optical imaging techniques: optical biopsy, IR Diaphanoscopy, IR thermography, Laser Doppler perfusion imaging (LDPI), Photoplethysmo-graphy imaging (PPGI), optical coherence tomography (OCT).
